BATH-TRAP.

intense.

Specification of Letters Patent.

Patented Apr. 19, 1221.

Application filed July 20, 1918. Serial No. 245,855.

Pennsylvania, have invented a new and useful Bath-Trap, of which the following is a specification.

My invention relates to improvements in bath traps. The object is to provide an imroved trap which is especially applicable or use with tubs without legs, where it is required that the inlet of the trap be at a low point so as to allow fall thereto from the tub.

The object is also to provide a construction which will prevent the siphoning of the trap, which will provide a large body of water to prevent the trap from becoming ineffective by evaporation, to provide a structure that will tend to be self-scouring, to provide improved means for cleaning the trap at different oints, and also to provide improved means or finishing to the floor.

Referring to the drawings which illustrate, merely by way of example, suitable means for the embodiment of my invention:

Figure 1 is avertical section.

Fig. 2 is a horizontal section on line 2-2 of Fig. 1. r 1

Similar numerals refer to similar parts throughout the several views.

Bath tubs to tile in floor without legs, require a trap in the waste line so designed that the inlet to the trap will be at a, low point so as to allow a substantial fall or drainage thereto from the tub.

This means a deep trap and one ordinarily difficult to clean, in case of stoppage.

In tiled-tub-nsage it is necessary to have the trap set so that the slag floor can be poured around it and worked to make a proper and permanent finish. This makes it desirable to provide clean out means which must be sewer gas proof and yet easily accessible.

Referring to Fig. 1, the chambered body 5 is provided with openings 6 and 7 with suitable means for pipe connections. 6 is the intake from the tub, and 7 is the outlet or discharge to the sewer connection. The opening 6 is as near as possible to the bottom of the chambered body and preferably directed at an angle of about fortyfive degrees-to the horizontal, so as to deso that the flow is thereby directed to a channel formation 9 leading to discharge port 7 This channel formation 9 is formed between the wall 8 and the partition 10. This partition 10 is shown as having a curved end 11 corresponding approximately with the curved portion of the wall 8. The lower end or apron portion of partition 10 serves as a protection to washer 17, against possible evaporation or partial siphonage.

Between this partition 10 and the wall 12 is provided a chamber or reservoir 13 capable of holding a substantial quantity of water.

Above chamber 18 is provided the horizontal wall or partition 1% having the aperture 15 adapted to be closed by the cap 16, threaded in said aperture, and provided with a compressible washer l7 engaging between the fiange of the cap 16 and the horizontal wall 14 to make a sewer-gas-proof closure. It will also be noted that this closure is slightly below the top of the bend 18 of wall 8, which is the normal water level in the trap, so that this closure is below the normal water level, to render the gas-tight closure additionally eflicient.

Above this horizontal wall 14 is the vertical extension 19 forming a chamber 20, provided in the present example, with an enlarged diameter at the top, as at 21, formed to receive, with a sliding or telescopic fit, the depending apron 22 of the flanged cap 23. This enlargement 21 also facilitates the access to plug 26.

In the wall of the extension 19 is provided the opening 25 directed toward the outlet opening 7 The tapered threaded plug 26, having the slotted end 27, is provided to close opening 25. It will be noted that the axis of opening 25 isinclined to the horizontal to facilitate the insertion of a cleaning device through said opening and also to facilitate the operation of the plug by means of a screw driver or other tool, through the top of chamber 20, when cap 23 is removed.'

It is also to be noted that cap 16 is provided with a suitable lug 24, for engagement with a wrench or other suitable tool for operating said cap.

A substantial surface 28 is provided surrounding the opening 6, which is especially dressed so that if it is desired to insert a pipe into opening 6 without being threaded therein, the same may be sealed with said opening by soldering a joint between the adjacent pipe surface and the specially treated surface 28. A similar surface is provided surrounding the discharge opening 7 The formation of the upper part of cham ber 20, for receiving the skirt 22 of cover plate 23 is such as to permit of considerable telescopic and angular movement to allow for adjustment with respect to the level of the floor above the top of said chambered body.

It will be noted that the chambered body has its longest dimension vertically arranged, and that the inlet opening 6 is as near the bottom of said body, and as far below the bottom of the tub, as possible so as to get a maximum fall of water from the tub to the trap. The inlet 6 is directed at an angle of forty-five degrees to the horizontal, so that the water is directed through the inlet 6 to strike the lower upwardly curving wall 5 of the chambered body, and thus carried upwardlywith a sweep and force that tends to scour said wall and reduce to a minimum any tendency for accumulations to gather in said trap. The curved end ll ofpartition 10 is so formed as to make a somewhat flaring opening for channel 9 which facilitates this direct current flow from inlet 6 to outlet 7, and without particularly disturbing the body of water contained in the reservoir 13. The outlet 7 is as near the top of the chambered body as possible, thus giving an extremely long and deep seal, which, in connection with trap, it'is only necessary to' remove the cap clean out the outlet, or the outlet PlPG'COlP nected therewith, it is only necessary to remove the tapered plug 26 in order to get access to said outlet and the adjacent coni nections.

As the main cleanout opening and the outlet clean-out opening have gas-tight closures, it will be obvious that the chamber 20 serves as a housing for these clean-out openings and closures and that the top or floor finishing cap 23 may have a loose sliding or telescopic lit in the top of chamber 20 and need not be either gas or liquidtight.

What I claim is I V 1. A bath trap comprising a chambered body having its greater dimension extending vertically, with an intake port at the bottom and an outlet port at the to a vertically extending partition within t e chambered body, near the central portion thereof, forming with the outer wall of the body, adjacent the outlet, a substantially vertical channel delivering to said outlet, and having its lower edge curving inwardly toward a plane through the axis of the body, said lower edge also terminating a substantial distance above the top of the intake port, whereby a partially closed chamber :or reservoir is provided entirely above said intake and outof the path of travel from intake to outlet, the outer wall which extends from the intake to said vertical channel, being curved sub stantially in the arc of a circle, and the in take being so arranged and positioned as to direct the flow in an unobstructed path along said curved wall to said vertical channel.

2. The combination as defined in claim 1, in which the body is provided with an opening at the top, and a cap 'is provided having a downwardl extendin fian elooselfittedy o in in said opening with sufiieient play to permit of telescopic and angular movement to allow adjustment with respect to the floor level.

3. The combination as defined in claim 1, in which the margins of the inlet and outlet ports are flanged and provided with especially dressed surfaces in planes at right angles with the axes of the openings as and for the purpose described.
